<span>The inferences I can make regarding the pH of a particular part of the digestive system is that it has a pH of 3. I know that 7 is neutral, and 8-14 is basic. I know that below 7 is acidic. The lower the number is from 7, the more acidic it is. I know that hydrochloric acid is quite acidic because I feel the burn from it when I get acid reflux attacks.
I think the relative size of carbon-based molecules are the size of a nickel, which I think is quite large. I think this because humans need carbon to live and a lot of foods contain carbon, so a lot of carbon molecules are broken down in the digestive tract.</span>
Answer:
Because earthworms do not like soil that is too acid, alkaline, dry, wet, hot or cold, their presence is a good indicator of soil conditions suitable for plant growth. Earthworms do not like acid soils with pH (CaCl2) less than 4.5. The addition of lime raises pH and also adds calcium.
Answer:
ATP is responsible for cocking (pulling back) the myosin head, ready for another cycle. When it binds to the myosin head, it causes the cross bridge between actin and myosin to detach. ATP then provides the energy to pull the myosin back, by hydrolysing to ADP + Pi.
Answer:
"Plate movement is thought to be driven by a combination of the motion of the seafloor away from the spreading ridge (due to variations in topography and density of the crust, which result in differences in gravitational forces) and drag, with downward suction, at the subduction zones."
